Frequently Asked Questions
How much output current can the UA78L15ACD supply?
The UA78L15ACD delivers up to 150mA of continuous output current at a fixed 15V regulated output. It includes internal current limiting, so the output current is automatically capped if load demand exceeds the rated limit, protecting both the regulator and downstream circuitry.
Can the UA78L15ACD be used in industrial temperature environments?
Yes. The commercial-grade UA78L15ACD is rated from 0°C to 125°C, making it suitable for industrial control boards, instrumentation, and enclosed equipment where ambient temperatures can reach 85–125°C. For sub-zero operation, consider the UA78L15AID industrial variant rated to -40°C.
What is the minimum input voltage needed for stable 15V output?
The UA78L15ACD requires at least 16.7V input (15V output + ~1.7V typical dropout) to maintain regulation. For reliable operation across full load and temperature, TI recommends keeping the input at 17–18V. Maximum input is 30V.
Are drop-in alternatives available for the UA78L15ACD?
Yes. The NCV78L15ACD (onsemi), MC78L15ACD (onsemi), and L78L15ACD (STMicroelectronics) are pin-compatible SOIC-8 alternatives with the same 15V/150mA specification. Always verify dropout voltage and quiescent current against your design margin before substituting.
What external components are required with the UA78L15ACD?
Minimal external components are needed: a 0.33µF ceramic capacitor on the input and a 0.1µF ceramic capacitor on the output are sufficient for stable operation. Adding a 10µF electrolytic in parallel on the output improves transient response for dynamic loads.
